Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mist sauna device having a controller for mist operation provided on a lateral wall surface in a sauna space.

[0002]

2. Description of the Related Art A temperature sensor for detecting the temperature in a sauna space is generally attached to the controller.
Further, conventionally, the temperature sensor is internally provided in the case of the controller so as not to be directly exposed to the outside.

[0003]

In the above-mentioned conventional technique, the temperature in the sauna space cannot be accurately detected, and there is a possibility that accurate temperature control cannot be performed. In addition, the temperature of the wall tends to be considerably lower than the temperature in the sauna space, especially in winter. Since the air in the case tends to stagnate and does not easily flow to the outside, the temperature in the case becomes low due to the temperature of the wall surface.
Further, when the temperature of the wall surface becomes low, the mist is condensed and adheres to the case, but the condensed mist may flow and adhere to the temperature sensor. Therefore, the temperature detected by the temperature sensor has an error from the actual temperature in the sauna space. An object of the present invention is to solve the above-mentioned conventional drawbacks and obtain a mist sauna device capable of accurately detecting the temperature in a sauna space without being affected by the temperature of the wall surface or the condensation of mist, and performing accurate temperature control. In point.

[0004]

In order to achieve this object, a characteristic structure of a mist sauna device according to the present invention is that a contact type temperature sensor for detecting the temperature in the sauna space is
Only the temperature sensitive portion is attached to the controller so as to be exposed on the front surface of the controller, and a protruding portion protruding forward is provided on the peripheral portion of the temperature sensor of the controller.

[0005]

Since the air in the sauna space circulates on the front surface of the controller, the temperature sensing portion of the temperature sensor is less affected by the temperature of the wall surface when exposed to the front surface of the controller. Moreover, even if the mist is condensed on the controller, it is possible to prevent the condensed mist from flowing and adhering to the temperature-sensitive portion of the temperature sensor by the protruding portion.

[0006]

Since the influence of the temperature of the wall surface and the condensation of mist can be eliminated, the temperature in the sauna space can be accurately detected.
As a result, it becomes possible to obtain a mist sauna device capable of performing accurate temperature control.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 3, the water heater 1 for supplying hot water to each of the hot water tap 5, the bathtub 2, and the mist nozzle 4 attached to the bathroom R1 as a sauna space is provided, and thus a mist sauna device is configured. The water heater 1 includes a heat exchanger 11 for heating water, a burner 12, a control device 13, and an ignition plug 14 as main constituent devices. A bath controller M1 as a controller for mist operation is provided on the lateral wall surface of the bathroom R1 and is connected to the control device 13. A main controller M2 is provided in the kitchen R2, and a mist controller M3 is provided in the washroom R3. In FIG. 3, S5 is a proximity sensor that detects opening / closing of the door D between the bathroom R1 and the washroom R3. Then, the mist operation is executed only when it is detected that the door D is closed based on the information of the proximity sensor S5.

The pipe path in the water heater 1 will be described. The hot water supply passage 6 from the heat exchanger 11 is the general hot water supply passage 61.
And a bath hot water supply path 62, and a bath hot water supply path 62
Is branched into a bathtub hot water supply passage 62A and a sauna hot water supply passage 62B. The general hot water supply passage 61 is connected to the hot water tap 5, and the bathtub hot water supply passage 6 is provided.
2A is in the bathtub 2 and the sauna hot water supply passage 62B is in the mist nozzle 4
Connected to each. The general hot water supply passage 61 is connected with a bypass passage 8 branched from the water supply passage 7 to the heat exchanger 11. In FIG. 3, V1 is a mixing valve for adjusting the mixing ratio between the hot water supplied from the heat exchanger 11 and the bypass water supplied from the bypass 8 in the general hot water supply path 61, and V2 is the bath hot water supply path 62.
, A bath valve for opening and closing, and adjusting the hot water supply amount in the bath hot water supply passage 62, V3 for a bathtub valve for opening and closing the bathtub hot water supply passage 62A, V4 for a mist adjustment valve for adjusting the hot water supply amount for the sauna hot water supply passage 62B, and V5 for a burner A gas valve for intermittently supplying gas to 12 and V6 is a gas amount adjusting valve. Further, 9 is a pressurizing pump for supplying hot water to the mist nozzle 4 under pressure.
Is a vacuum breaker.

A description will be given of the sensor configuration in the water heater 1. A heat exchanger 11 is provided in each of the water supply passage 7 and the general hot water supply passage 61.
A water amount sensor 16 for detecting the water supply amount Qi and a hot water amount sensor 17 for detecting the general hot water supply amount Qq are provided. A first thermistor S1 for detecting a water supply temperature Ti, a second thermistor S2 for detecting an outlet hot water temperature To of the heat exchanger 11, and a general hot water supply temperature Tq are respectively detected in the water supply passage 7, the hot water supply passage 6, and the general hot water supply passage 61. The third thermistor S3 is interposed.

As shown in FIG. 2, the bath controller M1 is provided with a hot water switch 20, a heat retention switch 21, a reheating switch 22, which turns ON / OFF the hot water bathing operation for the bathtub 2.
Mist switch 2 for turning the mist sauna operation on and off
3. A priority switch 24 for switching the priority to adjust the general hot water supply temperature and the room temperature of the bathroom R1 and a temperature control button 25 for adjusting the general hot water supply temperature and the room temperature of the bathroom R1 are provided.
Further, as shown in FIG. 1, the fourth thermistor S4 as a contact-type temperature sensor for detecting the temperature in the bathroom R1 has only the temperature sensing portion 40 at its tip exposed on the front surface of the case 30 of the bath controller M1. It is installed to do. Further, the case 30 is provided with a protrusion 31 protruding forward to surround the exposed peripheral portion of the thermistor S4. In the figure, 41 is a lead wire of the fourth thermistor S4, and 32 is a fourth wire.
It is a leaf spring that biases the thermistor S4 forward. or,
A liquid crystal display 26 is provided to display the operation status of the water heater 1. By the way, for example, if the mist sauna operation and the hot water filling operation are performed at the same time, the hot water supply capacity of the water heater 1 may be exceeded, so that the other operation is made to wait until one operation is completed. Basically ON later
The selected operation mode is preferentially executed, and the operation mode that was turned ON first becomes the standby. The operation mode during standby is displayed on the standby display unit 26a. Here, when a plurality of operation modes are in standby, the priority is represented by the numbers displayed on the standby display unit 26a. In the example of FIG. 2, the hot water filling operation and the warming operation are on standby, and the hot water filling operation has a higher priority than the warming operation.
